| titleOfInvention | The processing method of heavy metal wastewater thereby |
| abstract | The invention provides the processing method of a kind of heavy metal wastewater thereby, particularly the sedimentation method process the processing method of heavy metal wastewater thereby, sodium sulfide is added including when processing heavy metal wastewater thereby, sulphion and the heavy metal ion in waste water react generation particulate matter, add the sulfide precipitation of heavy metal further, stirring, standing, accelerate the sedimentation of finely ground particles and other materials by the particulate matter precipitation generated。The present invention, it is preferred that add quartz sand, accelerates the rapid precipitation of particulate matter and other materials under its encapsulation。Supernatant after precipitation processes through further subsequent technique, exchanges including sand filtration and ion, can qualified discharge；Regularly drain and collect partly precipitated thing, and return heavy metal therein。Due to this, processing method operation is simple, cost is low, and efficiency is high, and the method can be widely used for the process of industrial wastewater particularly heavy metal wastewater thereby。 |
